The Vista Content Protection specification could very well
constitute the longest suicide note in history.

...

This document looks purely at the cost of the technical
portions of Vista's content protection. [...] However, one
important point that must be kept in mind when reading this
document is that in order to work, Vista's content protection
must be able to violate the laws of physics, something that's
unlikely to happen no matter how much the content industry
wishes it were possible.

Read the whole piece, its hilarious.

The "remote shutdown" capability for device drivers, if
true is a reason enough to not buy Vista in any form or shape.
